Letters Patent No. 100,224, dated Flrruary 22, 1870.

-mPRovEMENT' IN APPARATUS POR Pnonocme BUTTER FROM CREAM The Schedulereferred to in these Letters Patent and making part of the :amr

To all whom 'it may concerli.-

Be it known thatv we, STANTON D. WARNR and OWEN W. THOMAS, ofRichrnonihin the county of Ii'icHenry, and State of Illinois, haveinvented certain new and useijnl Improvements in the Manufacture ofButter; and do hereby declare that the following is a full, clear, andexact description thereof', reference being had to the 'accompanyingdrawings audaci-he letters of reference marked thereon,

The nature of our invention consists in the construction and arrangementof an apparatus for mauui'act-uring butter from milk or creain bypressure and filtration.

1n order to enable Others skilled in the art to which our iuverrtionappcrtains tO make and use the sanre, we will now proceed to describeits construction and operation, referring to the annexed drawings, whichform a part of this speciticatiou, and in which- Figur 1 is aperspective 'view of our apparatus;

Figur 2 is a plan view ofthe plunger; and

Figure 3 is a vertical section of the` same.

A represents a circular vessel or cylinder of any suitable size placedwithin the trame B, andbaving a. plunger, E, operating within the same.

The plunger E, which is perforated with a numberl .of holes, as seen iniigs. 2 aml3, is hollow or concave on its under side, and in this cavityis placed some suitable fibrous filtering substance F, covered on theunder side with cloth.

The bottom of the cylinder A is also perforated, and on its ,upper sideprovided with asimilar cavity lled with fibrous substance and coveredwith cloth.

The filtering substance used in the bottom of the cylinder A nn'd inplunger E should be of sufficient density to prevent the butterysubstances of cream or milk from passing through, but, however,suticiently through' thc subject to this treatrncnt.

0n the'iramc B is an upright, to which s. lever, D,

is-piveterlyesid lever being at Monter'enfwnich is not shown in thedrawing, provided with n. weight.

To the lever D is pivoted a ba-r, C, which extends downward through theframe into the cylinder' A, :rnd

-may or may not be attached to the plunger E.

The weighted lever D causes the bar C to press the l plunger E down onthe milk or cream, when all the ser-ous or superfluous substances willbe pressed filtering-bottom and plunger, retaining the butterysubstances only. When this is accaniplisherl, the butteris taken out andworked in the usual way. v

The lever D can be` adjusted ou vthe upright to which it is pivoted, soas to accommodate the apparatus to any quantity of milk or creamdt-isdesired to Having thus fully described our invention,

What we claim as new, and desire to secure by Let ters Patent, is-

The construction and arrangement oi the cylinder A, having aperi'oratedconcave bottom, perforated concave plunger E, filtering substance F, barC, and adjustable weighted lever D, substantially as shown anddescribed.
